Beyond Presence is strongest when a product wants cloud-generated avatar video or a more complete managed conversational agent. Spatius is the more direct alternative when the product already owns its agent and wants to render the avatar inside its web or native client. The buying decision is therefore not only avatar appearance: it is whether the visual layer should deliver finished video or compact motion data.

Quick verdict: Beyond Presence or Spatius?
Beyond Presence describes its platform as real-time conversational avatars rather than prerecorded presenter video. Its Speech-to-Video API turns an existing agent’s audio into synchronized avatar media, while Managed Agents adds more of the conversation system. Spatius keeps a narrower boundary: Motion Server turns avatar speech audio into motion data, and AvatarKit renders the avatar locally.
| Decision area | Beyond Presence Speech-to-Video | Beyond Presence Managed Agents | Spatius |
|---|---|---|---|
| Product boundary | Cloud speech-to-video layer | Managed conversational video system | Client-rendered avatar layer |
| Existing voice agent | Keep it | Can replace more of it | Keep it |
| STT, LLM, TTS, tools | Your stack | More can be managed by the vendor | Your stack |
| Visual delivery | Synchronized media tracks | Managed avatar video experience | Motion data; AvatarKit renders locally |
| Published integration surface | LiveKit Python/Node.js plugin and Pipecat path | Hosted link, iframe, API, or embed | Web, iOS, Android, and Flutter AvatarKit clients |
| Published network figure | No comparable figure published on the reviewed pages | No comparable figure published on the reviewed pages | About 10–15 KB/s of motion data |
| Best fit | Existing agent that needs cloud avatar video | Team that wants a larger managed system | Existing agent that needs a native, replaceable visual layer |
The first comparison is Speech-to-Video versus Managed Agents. The second—and more consequential for a product team—is cloud-rendered video versus client-rendered motion. That choice changes network traffic, client responsibility, deployment reach, observability, unit economics, and who owns a production incident.
Route A: add Speech-to-Video to an existing agent
Choose Speech-to-Video when your product already has working speech recognition, reasoning, tools, text-to-speech, permissions, and analytics. Beyond Presence receives the generated audio and publishes the synchronized avatar output.
The official LiveKit Beyond Presence plugin supports Python and Node.js. A developer creates a normal LiveKit AgentSession, supplies a Beyond Presence avatar ID to AvatarSession, starts the avatar in the room, and then starts the agent session. LiveKit routes the agent’s audio to the avatar worker, which joins as a separate participant and publishes the synchronized media tracks.
The lower-level session API accepts an avatar ID plus a LiveKit URL and token; Beyond Presence’s documentation recommends using the LiveKit plugin rather than calling that endpoint directly. Pipecat is the corresponding choice for teams that prefer a frame-based voice pipeline.
Your model, tools, moderation, retrieval, and analytics do not need to move. Your team still owns interruption, retries, token expiry, participant mapping, and teardown.
Route B: buy the conversational video agent
Managed Agents is for teams that do not want to assemble every conversational layer. Beyond Presence documents configurable instructions, knowledge, branding, custom LLM support, voice cloning, transcripts, vision and perception, and website embedding. Feature availability varies by plan. The vendor’s AI agent stack guide explains how it positions the managed and composable routes.
This route can reduce assembly work, but ask whether it reproduces your model routing, tool policies, data controls, analytics, and escalation behavior. Test a complete workflow with real tools and failure states.
How the Beyond Presence and Spatius architectures differ
The products can accept the same upstream TTS audio while delivering fundamentally different outputs.
Beyond Presence Speech-to-Video path: your agent produces speech → LiveKit routes that audio to the Beyond Presence avatar worker → the worker joins the room as a participant → synchronized avatar media tracks are published to the user. LiveKit’s official plugin documentation shows this separate AvatarSession and participant model.
Spatius path: your agent produces avatar speech audio → Spatius Motion Server returns lip-sync motion data → AvatarKit plays synchronized audio and renders the avatar in the application. The Spatius architecture documentation publishes an approximately 10–15 KB/s motion-data path and states that finished avatar video does not need to be streamed.
This is not a small implementation detail. Beyond Presence turns audio into a provider-rendered media stream. Spatius separates cloud motion inference from the final pixels, so the end device owns rendering.
Where Spatius has a technical advantage
1. Lower published network payload
Spatius publishes roughly 10–15 KB/s for motion data because it is not sending finished video frames. Beyond Presence does not publish a directly comparable bitrate on the product and integration pages reviewed for this article. Buyers should therefore measure both products under the same resolution, frame rate, codec, region, and network rather than inventing a video estimate.
The architectural advantage is clearest for mobile apps, kiosks, shared Wi-Fi, or other environments where a continuous avatar video track is a meaningful part of the bandwidth budget.
2. Native rendering across more client types
AvatarKit supports Web, iOS, Android, and Flutter, and the final avatar is rendered inside the client. This gives product teams a direct path to native mobile or embedded experiences without treating the avatar as a remote video rectangle.
The tradeoff is real: the client must download avatar assets and have enough GPU, memory, and thermal headroom. A Spatius proof of concept should test the weakest supported device, not only a developer laptop.
3. A narrower, replaceable product boundary
Spatius does not replace the ASR, LLM, TTS, tools, retrieval, permissions, or conversation policy. That makes it easier to evaluate and replace the visual layer independently of the agent. Beyond Presence Speech-to-Video offers a similarly composable route, while Managed Agents deliberately takes ownership of more components.
Spatius has the clearest advantage when the existing agent is already strategic infrastructure and the team wants avatar rendering—not another agent control plane.
4. No permanent dependency on cloud-rendered pixels
Local rendering separates the avatar’s final frame production from a continuous cloud video renderer. That can improve delivery economics and client-side presentation control, but it does not make Spatius universally better. Beyond Presence is the better fit when provider-rendered video, its available avatar formats, or a managed end-to-end agent is the requirement.
Beyond Presence pricing: the same plan buys two minute pools
The current pricing page lists Free, Starter, Growth, Scale, and Enterprise plans at $0, $49, $149, $349, and custom pricing per month. The page displays usage rates in euros, so do not silently treat every figure as a single-currency contract.
| Plan | Speech-to-Video included | Managed-agent included | S2V overage | Managed overage | Concurrency |
|---|---|---|---|---|---|
| Free | 40 min | 20 min | — | — | 1 |
| Starter | 280 min | 140 min | €0.175/min | €0.35/min | 10 |
| Growth | 1,490 min | 745 min | €0.10/min | €0.20/min | 25 |
| Scale | 4,000 min | 2,000 min | €0.0875/min | €0.175/min | 50 |
| Enterprise | Custom | Custom | Custom | Custom | Custom |
The ratio reflects the ownership difference: Speech-to-Video consumes 50 credits per minute, while a conversational video agent consumes 100. The free plan currently limits sessions to three minutes; paid plans list unlimited session duration. Enterprise adds contract-level deployment and governance options, including isolated or on-premises deployment, SLA terms, zero-data-retention, and integration support.
Budget external voice-agent services separately for Speech-to-Video. For Managed Agents, confirm which model, speech, retrieval, storage, and overage costs are included. The avatar API pricing guide provides a neutral worksheet.
Run one proof of concept against both architectures
Use the same TTS audio, agent logic, region, conversation script, and network profile. Then record avatar startup time, first visible mouth movement, lip-sync drift, interruption behavior, weak-network degradation, reconnects, client CPU/GPU usage, full-session traffic, maximum session duration, peak concurrency, and the exact stock or custom avatar intended for production.
The comparison should answer five ownership questions: who owns turn detection, model selection, tool execution, conversation records, and user-facing recovery? It should also normalize cost. Beyond Presence Speech-to-Video still needs the external voice stack; Spatius also prices the avatar layer separately from ASR, LLM, and TTS. The Spatius LiveKit integration guide shows how to keep that client-rendered boundary inside an existing agent architecture.
Beyond Presence AI FAQ
What is Beyond Presence Speech-to-Video?
It is an audio-to-avatar layer for an existing voice agent. Your stack generates speech; Beyond Presence turns that audio into synchronized avatar video.
What do Managed Agents add?
Managed Agents add more of the conversational pipeline and deployment experience, including configurable agent behavior and embedded or hosted interaction paths. Confirm plan-specific feature access.
Does Beyond Presence work with LiveKit?
Yes. LiveKit documents official Python and Node.js plugin paths, and Beyond Presence exposes a lower-level session API for LiveKit transport.
Which Beyond Presence option is cheaper?
Speech-to-Video consumes half as many Beyond Presence credits per minute as the managed product, but your separate STT, LLM, TTS, transport, and engineering costs remain. Compare total cost, not only the vendor minute.
How is Spatius different from Beyond Presence?
Beyond Presence delivers provider-rendered avatar media and also offers a managed conversational agent. Spatius returns compact motion data and renders the avatar locally through AvatarKit on Web, iOS, Android, or Flutter while the customer keeps the surrounding AI stack.
Choose the output your product should own
Choose Beyond Presence Speech-to-Video when cloud-generated avatar video and its LiveKit or Pipecat integration fit the client experience. Choose Managed Agents when reducing assembly is worth transferring more of the conversation system. Choose Spatius when the existing agent should remain intact and the product benefits from compact motion delivery, local rendering, and native Web, iOS, Android, or Flutter clients.
